摘  要:
根据重庆永川区2002年到2008年遥感影像图,基于RS和GIS技术、ArcGIS9.2平台,对Landsat7、Landsat5卫星的ETM+和TM影像数据进行解译,得到该区研究时段的土地利用类型图。应用土地利用类型转移模型、土地利用类型面积的变化过程及土地利用程度时空演变模型,定性和定量相结合的方法分析了研究区7年间土地利用时空变化特征。研究表明:该区土地利用变化以耕地和园地为主。其中,耕地减少面积最大,变化率为-1.65%;园地增加面积最大,变化率为11.18%。耕地因区位条件和比较经济效益的差异不断向其他土地利用类型流转,耕地减少的去向主要是居民点及工矿用地,分别占各地类总面积的1.6%和3.4%。园地面积的增加主要来源于其他农用地及耕地的转化。研究区2002至2005年土地利用处于调整期或衰退期,2005至2008年土地利用处于发展期。

摘  要:
According to the remote sensing images from 2002 to 2008 in Yongchuan distrcit,Chongqing,based on RS and GIS technology,ArcGIS9.2 platform,this paper expressed the ETM+ and TM image data of Landsat 7,Landsat 5 satellites,to get the land use pattern in the area of study period and analyzed the spatial and temporal variation characteristics of land use in the study area during the past 7 years,using the land use types of transfer evolution model type area changes and degree of land use,spatial and temporal land use model,qualitative and quantitative method.Research result showed that:the land use change in this area mainly laid in cultivated land and garden plot.Among them,the reduction of cultivated land area was the largest,the change rate of-1.65%;garden increased the largest area,change rate is 11.18%.Cultivated land due to differences in location and comparative economic benefits transferred constantly to other land use types of cultivated land circulation,the reduced whereabouts was mainly residential and industrial land,which accounted for 1.6%and 3.4%of the total area of all types respectively.Transformation of garden area increase came mainly from other agricultural lands and arable lands.The study area from 2002 to 2005 land use was in adjust period or a period of recession,in 2005 and 2008 land use in development period.
